Certain features shown herein are similar to those shown in the patent granted to B. T. Headley and M. C. Bard, on the 20th day of February 1912, No. 1,017,870. Our present machine comprises a central stem 1 mounted on a table or platform 2, which is suitably supported by wheels whereby it may be moved to convenient points for operation, while rotatably mounted with respect to said standard is a table 3 upon which blank-molds 4, and blowmolds 5 are alternately disposed. The standard 1 carries a plurality of arms or brackets '1, 8, 9, 10 and 11, some of which are mounted on a sleeve 6, while others are mounted on other sleeves on the standard. The mounting of y the arms in groups will depend largely on the particular design of machine. These arms support'the several 7 valves and cylinders whereby the various operations upon bodies of glass within the molds may be accomplished, as hereinafter described, while the table 2 carries a rotatable member 12 with a series of vertically movable plugs 13 having mouth- 15 forming pins 14, andthe necessary valves, cylindersv and other mechanism to rotate the same, as well as to rotate the'mold-carrying table 3.

Figs. 1 and '7 show the machine in position for one of the blank-molds to receive a charge of glass, and such glass isdropped into a' blankmold 4 when in position A, ,(Fig. 8). when this is done, an operator actuates the shears 15 by, resting the gathering rod upon a controlling handle'l6, and the movement of this handle operates a rotary valve (such as shown at 13, in Fig. 6, of PatentENo. 1,017,870) controlling the delivery of air to a cylinder 1'? carrying a piston which serves to retract the'shears carrying mechanism and cause the blades of the. same to clos and sever the charge of glass in the mold from that carried by the gathering rod. The shears and operating mechanism therefor are carried. by the arm or bracket 7. (This mechanism is fully described in the patent above referred to and forms no part of the present invention.) 0n the return movement of a slidingrod 19 -em.- ployed for operating the shears, such movement opening said shears, a lever 20 pivoted at 21 is actuated, which lever has an arm 22 adapted to 0 contact with a valve stem 23 of a valve 25, and open said valve. Upon the continued rearwardmovement of the shears operating rod 19, the lever 20 is released, allowing said valve 25 to close. The'valve, however, has been open a sufficient 10B length of time toallow air .to flow from a branch a of a main supply pipe A through a pipe 2 to one end of a valve casing 26, within which-a valve 27 is contained, moving said valve to a position permitting the flow of air from the. main air supply pipe A to the several portions of the structure as hereinafter described.

As described above, the mold-carrying table has blank-molds 4 and blow-molds 5 set alternately adjacent its peripheral edge, and motion is imparted to this table in a manner substantially similar to the manner of operating the structure shown in Patent 1,017,870, or the machine of our pending application, before referred to; provision being made for stopping the machine at regular intervals; a complete revolution being made up of a series of quarter turn movements successively applied by the usual means set forth in the patent and application referred to.

Below the table and positioned to bring individual mouth fOrming pins into alignment with i the blank-molds when the latter are moved to' the charging position upon the partial movements of the table, is a rotatable member 12 substantially similar to the blank-mold carrying structure of the prior patent noted, and this member carries a series of vertically movable plugs 13, having mouth-forming pins 14; said member being toothed at 32 and meshing with a gear wheel 33 journaled on the. stem 1, and movable with the table 3 so that a fresh plug with a mouth-forming pin will be positioned for each movement of the table, ready for cooperative engagement with the. neck ring or mold of one of the blank-molds.

The plugs 13 are slidably mounted in cups 34 of the member 12 and have depending stems 35 forengagement by a yokemember 36 carried by a piston rod 3?, having a piston 38 in a cylinder 39 to which fluid under pressure is'admitted to raise and lower the piston rod 37 and with it one of the plugs 13 with its mouth-forming pin 14.

Glass is poured into one of the blank-molds,

preferably through an apertured plate 40, carried by a spring-supported arm 41 hung from a bracket 42, carried by t.-e arm 8, and after the glass has been poured into said mold and the-shears have been operated, a blow-head 43 is lowered; said blow-head being carried by a rod 44 connected to a piston i5 movable within a cylinder 46, supported by the arm 8, to which cylinder motive fluid is admitted in the usual manner; said piston red being hollow in order that air may be delivered through the same to the blow-head after the latter has been lowered into contact with the plate 40 over the blank-mold. This engagement moves the plate 40 into contact with v the blank-mold so as to permit a charge of air delivered by said blow head to enter the mold; forcing the glass in the same into a neck-mold 4'? positioned at the bottom of said blank-mold and around the mouth forming pin 14 of the plug 13, which finishes the mouth and efiects the formation of a recess in the blank or parison. When this operation is finished, the plug 13 with its mouth-forming pin 14 is withdrawn by the mechanism described, and then the table is given a quarter'turn, bringing the blank-mold into position for engagement with a lower blow-head 50 at station A which forces counterblowing air through the neck-mold into the recess at the mouth of the blank or parison, enlarging said recess and moving the glass upwardly against a plate 51 carried by a rod 52 depending from a piston 53 mounted within a cylinder 54, carried by the arm or bracket 9, to which cylinder air is admitted and exhausted, in the usual manner.

The lower blow-head 50 comprises an outer member 55 for engagement withthe table at the opening 30 through which the plug I3 rises for cooperation with the neck-mold, and a central member 56 having passages 57 for the delivery of air; a spring 58 being interposed between the parts 55 and 56 so as to keep the valve normally closed when not in action. This blowhead is carried by a piston rod 60 operated by a piston 61 within a, cylinder 62. Upon the conclusion of this operation, the table is moved another quarter turn to bring the mold to station A and an attendant opens the blank-mold, re-

moves the-blank from the'same by the aid of blank, which shell is movable with respect to an internal air delivery member 67 carried at the end of a rod 68, and forming with the shell 66 a valve. The rod 68 is connected to a piston 69 within a cylinder 70, carried by the arm or bracket 10; said piston being raised and lowered by air under pressure, anda spring 71 being employed to cushion the downward movement of the same as said blow-head 65 is brought into contact with the blow-mold. The table is then moved a quarter turn; the finished bottle being allowed to cool in- 'the blow-mold, and then the bottle is removed and transferred to a lehr in the usual or well known manner from the blow mold at station B The several valves controlling the operation of the structure, and the pipe conveying fiuid under pressure are shown in Fig. 7 and are more fully referred to in the description of operation, which is as follows:

The initial charge of glass is dropped into the blank-mold when in position A, Fig. 8. The shears are then operated, and on the return movement of operating rod 19 for the same, the

valve 25 is opened. The continued rearward I movement of the shears operating rod allows said valve 25 to close. However, this valve is open for a suificient length of time to allow air'to flow from the branch (1 of the main air supply A through the pipe 2 to one end of the valve casing 26, moving a piston valve 27 therein to such a position as to allow air to how from the main air supply pipe A through the said valve 27 to a pipe B connected to said valve casing 26, and its branches b, b and b The moving of the valve 27 also throws a pipe C and its branches 0 and c open to exhaust. Air under pressure supplied to the" pipe b is directed to the lower side of an equalizing valve casing 75, (carried by the arm or bracket 11) raising an equalizing piston valve 76 therein. Air flowing through the pipe 15 passes to an equalizing tank 77. Air supplied to the pipe I) is directed to one end of a valve casing 78, moving a piston valve 79 mounted within the same to a position in which pipes 11 and e are in direct communication with each other; the pipe C being open to exhaust, air is exhausted from one end of vah e casings 78 and 80 through pipes rected to the pipe D flows to the upper end of the cylinder 46 to act upon the piston 45 and lower the blow head 43 over the charged blank-mold 4, toforce the glass therein into the neck-mold and around the mouth-forming pin 14; the air being exhausted from the lower end of said cylinder 46 and one side of the valve casing 78 through the pipe E and its branches e and e.

The blow-head 43 controlled by the cylinder 46 is allowed to remain over the blank-mold tor a sumcient length of time to force the charge oi glass compactly around mouth-forming pin 14. This time is controlled in the following manner: Air flowing through the pipe b, (its progress being under the control of a valve 81) enters the tank 77 and flows from the same through a pipe :1: to the upper side of the equalizing valve 76 in the casing 75. when the pressure in this tank becomes equal to the pressure on the under side of the valve '76, (subject to the control of a pet cock 82 in the bottom of said tank, which pet cock is normally open) the valve in the casing is forced down, exhausting the air from the upper end of the cylinder 46 via the pipe D, and supplying air under pressure to the lower end of said cylinder via the pipe E and its branch e; thereby raising the blow-head from the blank-mold. The air directed to the pipe e flowsthrough the piston valve 79 in the casing 78, to the pipe 3;, and thence to one end of a valve-casing 85, moving the piston valve 86 therein against theaction of a spring 87. 7

Movement of the valve 86 in'the casing allows air to flow from the mainair supply A through said valve to a pipe F and its branches f, f, 1 P, f and f permitting a pipe- G and its branches g and g to exhaust through said valve 86. Air supplied to the pipe I is directed to the upper end of the cylinder 39 for action upon the piston 38 therein to withdraw the plug 13 and mouth-forming pin 14 from the blank-mold. Air

supplied to the pipe 1''. flows through avalve 90 in the casing 91 to a pipe :0 connected to the upper end of a cylinder 92, thereby withdrawing a locking pin from the rotating table 3. Air supplied to the pipe I is directed to the upper end of the cylinder 62 for action upon the piston 61 therein to lower the blow-head 50 from the under side of the table beneath the blank-mold; the cover 51 being raised from the top of said blankmold by air supplied to the lower end of the.

.trolled by said cylinder being raised from the blow-mold by application of air to the lower end of the cylinder 70 through the pipe F, to act upon the piston 69 therein. Exhausting the air frofn the pipe G and its branches g and a exhausts the air from the lower ends of the cylinders 39 and 62, respectively. I

As the piston 38 in the cylinder 39' is lowered by air supplied through the pipe f, the yokehead 36 01 the piston rod 37 strikes one end of a lever 95 pivoted at 96, while the opposite end of said lever, being in contact with the stem 97 pi! a piston valve 98 in a casing 99, raises said stem.

Raising the valve 98in the casing 99 supplies air under pressureto a pipe H and its branches h, h and h gan'd the raising of said valve places a pipe. I and its branches i,i', i and i open to exhaust through said casing.

-;.-Air applied to the pipe h flows to one end of a table-moving cylinder 100 which, throu'glfmechanism clearly set forth in our pending application, efiects movement of the mold-carrying table one-quarter of arevolution; a bracket 101 strikes the stem of a valve 106 in a casing 107;.

moving the same against the action of a spring 108 mounted onisaid stem. Air supplied to the 1 pipe'h. enters the lower end of a cylinder .110,

raising a piston therein so that the head oi. a

rod 111 carried by said piston will be in registry with the table moving pin 112 when the table moving arm 113 reaches the end of its movement.

Air is exhausted through the pipe I and its branches through pipei', from the upper end of the cylinder 54; through pipe i, from one end 0! cylinder 100; through pipe i from one port of the valve casing 91, and through pipe 1' from the upper end of the cylinder 110.

' When the bracket 101 moves away from the stem of the valve 90 in the casing 91, said valve is moved by a spring 105, thereby. cutting oi! the flow of air from the pipe 1" to the pipe 10 and cylinder 92, allowing a locking-pin controlled by said cylinder to rise against the under side of the table 3 inthe path of an aperture therein designed to receive the same. Communication between the pipe i and a pipe u leading to the valve-casing 80, is broken, and air is caused to flow from the main air'supply branch a to a pipe t, which delivers a supply of air to the blowhead 50 controlled by the cylinder 62.

when the table moving arm has completed its movement of 90, the locking pin enters an aperture in the table and holds it against further movement. The bracket 101? has then finished its movement and has moved the piston valve 106 in the casing 107, permitting the flow of air from the pipe h? to a pipe S which leads to one end of the valve-casing 26. This moves the valve 27 therein and startsthe machine on its return movement as follows: d

The movement of the valve 27 in casing 26 exhausts air from the pipe B and its branches b, b and b from the equalizing valve-casing 75, tank '77, and one end pf valve casing 78. This same movement directs air from the main air supply A to the pipe 0 and its branches 0, c. The air being exhausted from one end of the valve-casing 78 and applied at the other end' through the pipe 0'; the piston valve 79 therein is moved, exhausting the air from the valve-' casing 85 via the pipe y. Exhausting the air from one end of the piston-valve in the casing 85, permits a spring 87 therein to move said valve to a position permitting the exhaust of air from upper end of said cylinder causes the piston 38 'to raise a plug 13 with a mouth iorming'pin 14' into the bottom oi. a blank-mold. During this movement, the head 36 moves away from the lever 95, allowing the piston-valve 98 in the chamber 99 to descend under the influence of its spring 97. Air applied to the lower end of the cylinder 62. via pipe 9' and exhausted from the upper end via-*pipe f raises the piston 61 to lift the blow-head'50 controlled thereby against the said cylinder via pipe f 4. As the blow-head 50 is at this time supplied with air under pressure from the line A, branch (1 and pipe t, it will deliver air into the cavity formed by. the neck pin to form a. parison and prevent the glass in the mold from collapsing. The air is exhausted from the cylinder 54 via pipe F. Air is exhausted from the lower end of the cylinder '70 via pipe I and from one end of the valve 93 in the casing 80 via pipe f and air being applied to the opposite end of said valve 93, it is moved into a position allowing direct communication between the pipes u and v.

Lowering the piston-valve 98 in the chamber 99 exhausts air from the pipe H and its branches h, h and h and applies air under pressure to the pipe I and'its branches 2, i, i and i Air directed to the pipe 2' and exhausted via pipe h, will lower the piston in the cylinder 110, and withdraw the table moving pin 112 from the table.

Air directed to the pipe z" lowers the piston 53 in the cylinder 5 bringing the cover plate 51 v down over a blank-mold, and when air is directed to pipe 5 and exhausted from pipe in, the piston in the cylinder 100 is retracted. Upon the initial movement of such retraction, the bracket 101 moves away from the valve-casing 16?, allowing the piston valve 106 therein to be moved by its spring 108, closing communication between the pipe 11 and the pipe s.

When nearing the end of its return movement,

the bracket 101 again strikes the stem 103 of the valve 90 in the casing 91, moving the valve therein. The movement of this valve establishes a direct passage between the pipes f and w; i and u, and cuts oii passage between pipes a and t.

The communication between i and 2;. allows air to flow from pipe through the pipe a, valve 93 and pipe 1) to the upper end of the cylinder 70, thereby lowering the blow-head controlled by said cylinder over the blow-mold; the air having been previously exhausted from the lower end of The communication established between the pipes o and t supplying air to the blowhead 50 controlled by the cylinder 62 during the rearward movement of the arm 113 is cut off at the completion of its movement.

At the end of the backward movement of the table moving arm 113, the pin 112 enters an aperture in the table, ready to again move the latter a quarter turn, or 90".

The manner of operating the machine in the.

' formation of the blanks or parisons and the finished, blown, bottles, is more fully explained by reference to the diagrammatic view, Fig. 8, in which a. series of blank-molds d are shown in positions A', A A and A alternating with a series of blow-molds 5, shown in the positions A' represents a blank-mold in the charging position. After the charge of glass has been acted upon by the pressure of air from above to lower it in the mold and cause it to form around the end of a mouth forming pin and within the .neckmold, and said mouth-forming pin has been withdrawn, the table is moved a quarter-turn by the means referred to; bringing said blank-mold to the position A At this point a cap plate is lowered onto theblank-mold, and pressure from the lower blow-head 50 lifts the glass within the mold to form the complete parison. When this is completed, the blow-head andcap plate are withdrawn and the table again moved a quartertum; bringing the blank-mold to the position- I 1,948,219 under side of the table 3, beneath a blank-mold A The blank-mold is now opened and an attendant removes the blank, inverts it, and places it in a blow-mold at position 3'. The table is again moved a quarter-turn, bringing the blankmold to the position A and the blow-mold to the position B. This permits' the blank in the blow-mold to set slightly and the blank-mold to a cool. The table is then moved another quarterturn; bringing the first-mentioned blank-mold to Y' tle is allowed to cool, and the freshly-charged (first-mentioned) blank-mold is advanced to position A On the next quarter-turn of the table, the blow-mold advances to the position 3' where the finished bottle is removed, and the blank-mold with the finished parison is brought to the position A Immediately after the finished bottle is removed from the blow-mold at B', the finished parison is taken from the blank- -mold at A and inserted in said blow-mold at B', as before set forth. This sequence of events is carried on continuously in the operation of the machine; the finished bottles being carried to a suitable lehr when taken from the blow-mold at position 3'.
